good way to get rid of pond aglae without using a uv sterilizers or chemical

  • We are currently upgrading MFK. thanks! -neo
paint it black! I don't see any algae grow in my black tank!
 
More plants. thats all you can do unless you wanna spend money. just get hornwort and other awesome plants they will suck out the nutrients before the algae does
 
You are correct about the cost of UV sterilizers. Plants will work for a lightly stocked pond but most people keep more than a few oversized fish. Plants actually clog filtration and too much plants can actually deplete the water of oxygen. Great tip on the balance of the ecosystem.
They do make UV for lakes.

How does something that takes in co2 and off puts pure oxygen, equate to depleated oxygen?
 
just use bullfrog tadpoles. im not 100% sure its gonna work. but I only heard they eat algae. just feed them ground up flakes and sadly they will grow to frogs. ur koi will eat the eggs to controll their population.

trouble is koi will eat the tadpoles and the baby frogs before they get big enough...found that out the hard way. I also prefer plant filtration for algae and nitrates. As long as you're a diligent pond keeper it won't be an issue with cloging the filter.
 
most people use UV on their ponds... plants, less sun light and chemical are not very useful to control aglae on outdoor

You are correct about the plants during the day but at night the plants absorbs oxygen giving off CO2 forming carbonic acid which lowers the pH. I've been called many times in the morning about kois dying overnight.
 
Just finish builting it and wanted everyone to see my upgrade or add on to my pond. It a home made trickle protein skimmer. It will get rid of aglae, waste and more. I am running it with one pump to my 2 filter and the 1 skimmer. I am going too hide this skimmer in my brushes. My pond water is clear but as you can see skimmer water is not. Have not test it in green water yet. It should even work better in green water or overstocked fish water.

nice DIY. Do you have anything in the tall tube itself shearing the water is it just the fall from that height?
